AMD Athlon 64 3200+
Pentium 4 560 (3.6 GHz)
The AMD Athlon 64 3200+ isn't always an AMD Athlon 64 3200+. Yes, they both have the same performance-rating but they don't always have the same clockfrequencies and L2-cache sizes. This phenomen is not new: the AMD Athlon XP 2600+ comes in three different variations as well. Even Cyrix already based their performance-rating on a combination of clockfrequency and front-side-bus speeds with the Cyrix MII CPU's.
In this case the Athlon 64 is based on the New Castle core. Almost all New Castle Athlon 64's have 512KB L2-cache whereas the earlier ClawHammer based CPU's could have up to 1MB L2 cache.
I haven't benchmarked this particular CPU yet but performance differences aren't that big and vary per application. The New Castle 3200+ has half the L2-cache but a 200MHz higher clock (2200MHz). The ClawHammer fares with 1MB L2-cache and a 2000MHz CPU clockfrequency.
